Answer:
5x - 30
Step-by-step explanation:
5 must multiply with what's in the bracket for being next to it
5 x X = 5x
5 x -8= -40
5x - 40 + 10
- 40 + 10 = -30
5x - 30
Answer:
-30+5x
Step-by-step explanation:
5(x-8)+10
x-8 evaluates to x-8
Multiply 5 by x-8
we multiply 5 by each term in x-8 term by term.
This is the distributive property of multiplication.
Multiply 5 and x
Multiply 1 and x
The x just gets copied along.
x
5 × x = 5x
Multiply 5 and -8
1
5 × -8 = -40
5*(x-8) evaluates to 5x-40
-40 + 10 = -30
The answer is -30+5x
5*(x-8)+10 evaluates to -30+5x
Answer:
3
Step-by-step explanation:
5200 – [40%(300 * 42.5)]
Answer:
The value of the expression is 100
Step-by-step explanation:
we have
5,200-[40%(300*42.5)]
we know that
(300*42.5)=3*100*42.5=3*4,250=12,750
40%=40/100=0.40
substitute
5,200-[0.40*12,750]
5,200-5,100=100
